    This is most likely a tech support scam, not a real Microsoft lock. Microsoft error and warning messages never include phone numbers, and Microsoft does not make unsolicited phone calls or display browser pop-ups asking for payment or support.

    Try these steps to unlock the PC:

    1. Do not call any number shown on the screen and do not enter passwords or payment details.
    2. If the alert is in a browser window, press Ctrl + Shift + Esc to open Task Manager.
    3. In Processes, find the web browser that is showing the alert and select End task.
    4. Reopen the browser. If prompted to restore the previous session or pages, select No.
    5. If Task Manager cannot be opened, press and hold the power button for at least 10 seconds until the PC turns off, then turn it back on.
    6. Run a full scan with Microsoft Defender Antivirus and install all available security updates.
    7. If any remote-access app was installed or any information was shared, uninstall that app, change passwords, and monitor sign-in activity.

    For live Microsoft help:

    • Use the sign-in helper if the issue involves account access.
    • Use Get Help or Contact Support for technical support.
    • If support is needed for malware or virus concerns, Microsoft also provides virus-related support options.

    Can you please hold down Ctrl+Alt+Del, then launch Task Manager, and then end all browser items there to close it. That page is definitely scam, but as long as you didn't call the number and engage in any of the requested activities, your computer is not hacked. It is just a pop up page that can have some audio effect (sometimes) and display in full screen mode, so it appears the computer is locked.

    Scammers use various methods to trigger these pop-ups. Pop-ups are a form of online advertising. They are often integrated into websites or applications through ad services. Many websites use third-party advertising services to display ads. Sometimes, these ad services might inadvertently allow scam ads to be displayed. This does not mean the website itself is malicious, but it indicates a lack of stringent ad vetting.
